since I know Sylvain. But he's truly a good guy as well as a skilled watchmaker. He got Meilleur Ouvrier de France honour with his chronograph and this is not a light thing to get. Making a chronograph is probably one of the most complicated thing. And mirror finished steel parts are jaw dropping. I
